I. INTRODUCTION
From the start of the “New Order” government in 1966 up until 1997,
However, the Asian Financial Crisis in 1997 brought a sharp halt to this economic miracle. Between 1997 and 1998 annual GDP growth in Indonesia fell by 13 percent and the incidence of poverty increased by 7 percent. The events of
For this reason, the current recession in Europe raises deep concerns about the possible impact of these events on the Indonesian economy. However, to date there has not been any quantitative analysis of the possible impact of these events on economic growth and poverty in Indonesia. The purpose of this paper is, therefore, to provide a
The objective of this paper is to use general equilibrium models to quantitatively assess the impact of the current recession in Europe, Japan and China on Indonesian poverty. It is expected that the results from such a general equilibrium analysis will give us important insights on how to design appropriate policy instruments for protecting the Indonesian economy from external disturbances.
The next section of this paper outlines the theory and the structure of the model. Section three outlines the data and the methodology, including the scenario of simulation. Section four provides result and analysis, while section five gives conclusion and the policy implications.
II.THEORETICAL FRAMEWORK AND EMPIRICAL LITERATURE 2.1. How external shock can affect poverty
It should be clear that what it means by external shock is in the context of exogenous change from the country’s persepective. In this case, those shocks can be a recession in a particular country, a group of countries, or one or some regions. The shocks can also be international price of commodities determined in the world market exogenous to the perspective a a particular country or the assumption of Indonesia being a small open economy.
Poverty should also be defined clearly. There are many dimension of poverty, but in this particular study, the focus is on expenditure poverty which is quantitatively measured as

The effect of external sock on poverty incidence
The impact of an EJC recession on the Indonesian economy can work through various channels, including trade, foreign direct and portfolio investment, and other monetary or financial channels. In this analysis, the focus is on the impact through the trade channel. A recession in the EJC countries will reduce imports and exports from countries like Indonesia. The impact on the Indonesian economy is likely to be negative, and the magnitude of the impact depends largely on the share that these countries have in Indonesian exports. This is the direct
210Buletin Ekonomi Moneter dan Perbankan, Volume 18, Nomor 2, Oktober 2015
trade effect. The indirect trade effect is rather unclear. The reduction of imports from Europe, China and Japan will tend to reduce the world prices of commodities. Global deflation like this may reduce Indonesian exports yet increase Indonesian imports.
On the other hand, the decline in the export of goods from the EJC countries may increase the world prices of commodities. To some countries (including Indonesia), this might represent an opportunity to increase exports and to raise world market share. This effect tends to work positively for the Indonesian economy. To complicate things, these effects work differently among different countries, each with a different type of repercussion on the Indonesian economy. Therefore, the overall net impact on the Indonesian economy is difficult to predict and calls for a computable general equilibrium analysis.
The effect on poverty depend on the general equilibrium outcome of prices or new equilibrium prices changed due to the external shocks. There are two kind of prices that at the end will affect through different channels to households. First of all is the price of factors of production will affect household income. The impact on households will be different even though all households face the same price of capital or labor because poor and
Another channels is its impact on price of commodities. Again, although all households face the same price of commodities, the composition of household ecpenditures may differ. Poor household may buy less of travels but more of rice, while rich housholds may buy more of gasoline and other luxurious items.
The final impact on these two channels are on the real expenditure, or expenditure per capita. Poverty incidence then is used based on this real expenditure per person before and after the shocks and the difference is calculated as the impact of external shocks on poverty incidence.
2.2. Empirical literature
There have been some studies looking at the of global crisis, particuarly the
Wong, (2012) quantifies the macroeconomic and poverty impacts of the
External Shocks And Poverty: How Recession In Europe, Japan, and China Affects The Indonesian Poor 211
in capital returns and wages of skilled labor. These factors are used intensively in the oil sector, a key sector of the Ecuadorian economy, and one of the hardest hit by the global crisis. There are differentiated poverty impacts: poverty may increase if labor is assumed sector specific, and it may be reduced if labor were mobile.
(Habib, Narayan, Olivieri, &
Using a microsimulation analysis, (Ajwad, Francisco, & Azam, 2012) look at the distributional impacts of the 2009 financial crisis on households in Latvia. The simulations show that Latvia experienced a sharp rise in poverty, widening of the poverty gap, and a rise in income inequality due to the economic contraction in 2009. The 18 percent contraction in gross domestic product (affecting mainly trade hotels and restaurants, construction, and manufacturing) likely led the poverty head count to increase from 14.4 percent in 2008 to 20.2 percent in 2009.
(Ahmed & Donoghue, 2010) adopt a
(Weeks, 2009) using a macroeconomic model finds that the global financial crisis will cause a fall in export earnings in Sierra Leone of approximately fifteen percent in 2009 compared to 2008. He find that this decline in exports earnings could result in a fall in national income of almost ten percent and based on the income distribution in the 2003 household survey, a ten percent decline in national income would increase poverty by twelve percent of th population, or about 600,000 people.
(Habib, Narayan, Olivieri, &
212Buletin Ekonomi Moneter dan Perbankan, Volume 18, Nomor 2, Oktober 2015
(Bibi et al., 2010) evaluate the potential impacts of the 2008/09 global economic crisis on child poverty in Cameroon. A dynamic computable general equilibrium (CGE) model is used to simulate various scenarios of the economic crisis together with policies which respond to the crisis. The study shows that the crisis is projected to lower the real GDP growth rate by 1.3 percentage points in 2009, 0.9 in 2010 and 0.8 in 2011. The crisis would also bring about a 1.05% increase in the number of children who were poor in monetary terms in 2008 and a 4% increase in 2009, 2010 and 2011, compared to the situation without a crisis.
In their analysis, (Estrades & Llambi, 2013) evaluate the impact of the 2008 global economic crisis on Uruguayan economy through two main channels: collapse in global trade and drop in capital flows. They apply a computable general equilibrium model linked to microsimulations to analyze the distributional impacts of these policies and assess their effectiveness. They find that an increase in public investment was the only policy effective in mitigating the negative impact of the crisis on extreme poverty.
In a study which focus on conceptual framework with the application to Vietnam, (Coxhead, Linh, & Tam, 2012) present a framework for understanding the direct and indirect welfare effects of a global market shock. They quantify transmission of the shock from global indicator prices to domestic markets. Then they use an applied general equilibrium model to simulate the economic effects of the price changes. A recursive mapping to a nationally representative household living standards survey permits them to identify in detail the ceteris paribus effects of the shock on household incomes and welfare. In this analysis, interregional and intersectoral labor market adjustments emerge as key channels transmitting the effects of global price shocks across sectors and among households.
(Corong & Taningco, 2011) analyzes how the global crisis may have affected the Philippine economy. To the extent that the Philippines is more globally integrated through trade and labor flow channels than the financial sector, it is expected that impact of the global crisis will weigh heavily on the “real” side of the economy. A dynamic computable general equilibriu m (CGE) model linked to a
To summarize, most of the studies above suggests that global financial crisis affect the poor negatively. However, the magnitude is different; there are exceptions where the impact on poverty is negligible because the crisis affect mostly the rich; and policy responses can have significant impact on the final effect of the crisis. There is however, a methodological gap in most of the studies in how they linked global shocks into the national model. The analysis could

not really explicitly attribute the shocks to a recession in a specific countries or regions. This is because they only use a national model. In this paper, two models will be used, a global or
III. METHODOLOGY
To estimate the impact of recession in Europe, Japan, and China on Indonesia’s economy, we use the Global Trade Analysis Project (GTAP) model, a
To reflect a reasonable magnitude of recession, we compare the forecasts of country GDP presented in the IMF’s World Economic Outlook database of 2009 and 2011. Forecasts of European GDP for 2012, 2013, and 2014 are then compared assuming that the forecast in 2009 is business as usual and the forecast in 2011 already reflects the European crisis. On the basis of this comparison, we calculate that the European recession can be defined as roughly a 2 percent deviation of GDP below baseline. We use this 2 percent deviation to simulate the endowment of primary factors in Europe, Japan, and China.

The production of each sector in each country is represented by a nested production function which is a combination of a Leontief, Constant Elasticity of Substitution (CES) specification. This kind of a nested or staged production is a convenient way of representing separable, constant

IV. RESULTS AND ANALYSIS
Results from our GTAP simulation suggest that Indonesia is not among the countries most heavily affected by a recession in Europe. A 2 percent decline in Euro zone countries’ GDP reduces Indonesia’s GDP by only 0.052 percent relative to baseline. A 2 percent decline in all 27 countries members of the EU still reduces Indonesia’s GDP by only 0.078 percent relative to baseline (Table 1).

Table 1 shows that the countries most negatively affected by a European recession are those in the Middle East and North African (MENA) region. With a 2 percent fall in the EU’s GDP, MENA’s GDP falls by almost 0.6 percent, an elasticity of 0.3. Europe is the biggest importer of this region’s energy and MENA countries are heavily dependent on energy exports.
In Asia, Singapore is the country most affected by a European recession because of its dependence on international trade. Japan and China, however, experience a slightly positive increase in GDP.
If China and Japan experience a recession of similar magnitude the impact on Indonesia’s GDP will not be stronger than the impact of the European crisis. But the impact is disproportionate because Japan and China are single countries while the EU consists of 27. A 2 percent decline in China’s GDP causes a 0.07 percent decline in Indonesia’s GDP and a similar decline in Japan’s GDP causes a 0.03 percent decline in Indonesia’s GDP. In other words, China’s potential impact on Indonesia is almost twice that of Japan’s.
The impact of recession in Japan will be felt most in Singapore, where GDP will fall 0.24 percent, and the impact of recession in China will be felt most in Thailand, where GDP will fall
0.33percent relative to baseline. Singapore and Thailand are among the most open economies in Asia.
218Buletin Ekonomi Moneter dan Perbankan, Volume 18, Nomor 2, Oktober 2015
In sum, a European recession of a sensible magnitude (2 percent GDP deviation relative to business as usual) working through full trade linkage (taking into account indirect trade effects through other countries as well) will not have a very large negative impact on Indonesia’s GDP. The reason for this is that Indonesia’s economy depends little on external trade. This does not mean that European recession will not affect the world economy to a considerable extent; other countries, like Singapore and MENA countries, will be greatly affected.
With respect to poverty in Indonesia, the impact of a recession in Europe, Japan, and China is also small. A combined 2 percent decline in GDP in Europe, Japan, and China will increase Indonesia’s national poverty head count by only 0.19 percent (Table 2). The biggest impact will be if the recession is in either China, or all of the EU. The impact on a recession on poverty in Indonesia is small because (1) the impact on overall mean real consumption is small and (2) the impact is most strongly felt among higher income households.
As suggested in Figure 1, where percentage change in real expenditure is plotted on the percentile of expenditure per capita, the impact of recession in Europe, Japan, or China is similar. The impact increases with income status. For example, the effect of a recession in the Euro zone on real consumption of the richest 1 percent of urban households is 3 times bigger than on the poorest 1 percent. Similarly, the richest 1 percent of rural households experiences a decline in real consumption 4 times bigger than the poorest 1 percent. The result is similar in all simulations (Euro zone, EU, China, or Japan recession). The range of the ratio of the impact is between 2.3 to 2.9 for urban households, and between 3.3 to 4.4 for rural households. This suggests that the simulations have an
The distributive effect discussed earlier can be explained by how recession affects (1) household income, particularly return on factors of production; and (2) the pattern of change in the
Global recession tends to decrease the global prices of commodities. Transmitted to the Indonesian economy, this deflationary effect will tend to reduce commodity prices for domestic consumers. A careful look at how this affects households of different income status suggests that the effect is only slightly progressive if not neutral. Across all simulations, the ratio of the impact on
Figure 2, which shows the simulated impact of recession in Europe, Japan and China on real income of different factors of production, explains this. Almost all factors of production experience real decline in income; however, the biggest decline is where ownership is concentrated among higher income households. Capital income declines more than labor income, and skilled labor income declines more than unskilled labor income. This pattern of impact favors poorer households whose incomes largely depend on unskilled labor.

Figure 3.
Simulated Impact on Output of Aggregated Sectors (% change from baseline)
222Buletin Ekonomi Moneter dan Perbankan, Volume 18, Nomor 2, Oktober 2015
The pattern of impact on production factors income is largely driven by how industries respond to trading partners’ recession. As shown in Figure 3, the simulated recession in Europe, Japan, and China negatively affects output in certain sectors, most notably oil, gas, and other extractive sectors. These sectors are capital- and
A closer look at the impact on poverty suggests that rural areas would be harder hit than urban areas (Table 2). For example, a recession in Europe, Japan, and China combined would increase the incidence of poverty in urban areas by 0.10 percent and in rural areas by
0.28percent. To understand this, we examine what happens to real consumption in marginally poor urban and rural households. A marginally poor household is one whose expenditure per capita is closest to the poverty line. Knowing what happens to these households shows how the simulation affects poverty incidence.
As explained in Warr, Menon, and Yusuf (2012), The basis for the decomposition is as follows. We focus on the sources of changes in the real expenditure of a particular household, say household h, arising from some external shock. Upper case Roman letters, like Z, will denote levels of variables and lower case Roman letters, like z, will denote their proportional change, so that z = dZ / Z. The levels of nominal income and nominal expenditure of household h will be denoted Yh and Eh, respectively. Let the proportional change in the nominal expenditure of household h, be eh = e~h + ph, where e˜h is the proportional change in the household’s real expenditure and ph = ∑iI=1ε hi pi is the proportional change in a consumer price index specific to household h, with ε hi = Ehi / Eh denoting that household’s expenditure share on commodity i, Ehi denoting its nominal expenditure on commodity i and pi denoting the proportional change in the consumer price of commodity i.
The absolute change in this household’s nominal expenditure is now

That is, the change in nominal expenditure of the household is given by the change in its real expenditure plus the change in its true cost of living, the latter an expenditure weighted sum of the changes in the consumer prices that household actually faces, where the expenditure weights pertain to that particular household.5 The change in nominal expenditure is also equal to the change in nominal income minus the change in saving, so that dEh = dYh − dSh. Disregarding any changes in transfer income or direct taxes, for simplicity, the change in nominal income is equal to the change in nominal factor income, dYh = dYhf .
5It should be noted that real expenditures means expenditures measured at constant prices, defined here to mean base period prices. Thus, the levels of nominal and real expenditures in the base period are identical, meaning Eh = E˜ h.

Thus, rearranging terms,
I
dE˜ h = dYhf − dSh − ∑Ehi pi
i=1
The change in the household’s real income is decomposable into three components: (i) the change in its nominal factor income minus (ii) the change in its savings minus (iii) the change in its true cost of living. Importantly, the change in nominal factor income is itself additively decomposable into its factor components, as identified in the model.
This decomposition is applied to those households are those who are in the border of poverty line. They are percentile 8 household in urban area and the percentile 15 in rural area. What happens to these two representative households may explain what happens to poverty incidence.
As shown in Table 2, the percentage change in the real expenditure of marginally poor households in urban and rural areas does not differ much. For the combined simulations, for

example, marginally poor households in urban areas experience a 0.34 percent decline in real consumption while those in rural areas experience a 0.37 percent decline. This much larger impact on poverty incidence in rural areas suggests that the elasticity of poverty incidence with respect to the change in the real consumption of marginally poor households is relatively larger. The slope of the cumulative distribution function (CDF) of the real consumption of the rural households around the region of the poverty line must be higher than that of urban households. With the same magnitude of change in their consumption, the rural poor are more vulnerable to external shocks than urban households.
It is also useful to understand to what extent change in the real expenditure of the marginally poor household is driven by its decomposable drivers. The decline in the real expenditure of the poor can be generally decomposed into income effect (decline in income) and consumer price effect (increase in the price of the commodity basket of the poor or living cost). The income effect can also be decomposed (e.g., labor income, capital income). Table 2 shows how it is the case for urban and rural marginally poor households. Several conclusions can be drawn from this decomposition exercise.
First, the
V. CONCLUSION
The effect of a recession in Europe, Japan and China on other economies through trade linkage depends on many factors. These factors include the importance of bilateral trade between the affected countries or regions, the openness of the economy, and the country’s level of diversification in export commodities and trading partners.
The impact on poverty in the affected countries depends even more on various country specific aspects such as how the poor earn its income and how the spend their earning. If bigger part of its source of income are affected by the global crisis and the price of the commodities they intensively consumed are heavily affected, then the poor will be vulnerable to external shocks. This is empirical and this paper touch this important issue.
This paper shows that the impact of a recession in Europe, Japan, or China on Indonesia is relatively small simply because Indonesia is a relatively less open economy and depends

predominantly on its domestic market. According to our analysis, the current recession in Europe, Japan and China will have only a small negative effect on Indonesia’s GDP and poverty rate.
However, results suggest that it would be wise to pay attention to China. According to our simulation, a recession in China could reduce Indonesia’s GDP two times more than a recession of similar magnitude in Japan.
This analysis shows that a recession in Europe, Japan, and China would have its largest negative impact on richer households in Indonesia. Richer households would suffer the most because their incomes are largely dependent on the capital- and
Finally, our analysis does not cover the effects of recession in Europe, Japan and China on economic channels other than trade, such as foreign direct investment and the financial sector. The general equilibrium model used in our analysis does not cover the financial sector, so other studies focusing on this channel are warranted. In addition, in the longer term, poverty is affected by various factors other than income and prices. Human capital accummulation, sosial assitance policies and equality of opportunity are important in poverty alleviation. This effects are not accounted for in this analysis.
